Overview of parametrisation: physical master with
slave (FNUM=1/2)
6.1.1
Control of the physical masters
In controlling the physical master, no cam-disc specific special features need to be
observed (standard FHPP: record selection or direct operation).
6.1.2
Control of the slave (FNUM=1/2)
The slave can be controller via fieldbus either by record selection or direct operation.
For record selection:
1.
You pass on the desired
record number
over the FHPP control byte 3.
2.
In the
record control byte 1
(RCB1), you determine whether a positioning record
should be executed as a normal positioning record or whether the drive should run
down a cam disc instead. This happens through an entry in the subindices of PNU 401:
Set bit 7 (FUNC) to “1” and choose the desired function via bit 3 and 4 (FNUM).
3.
Parametrise the
cam disc number
individually for every record over the subindices of
PNU 419. If no cam disc number is stored in PNU 419, the controller uses the cam disc
number according to PNU 700.
4.
Start:
The cam disc mode is started through a rising edge at the START bit CPOS.B1.
Examples for configuration of the controller: see sections 6.9.1 and
6.9.2.
With direct operation:
1.
You determine in the FHPP control byte 3
CDIR
that the slave synchronises on X10: Set
bit 7 (FUNC) to “1” and choose the desired function via bit 3 and 4 (FNUM).
2.
You pass on the desired
cam disc number
via PNU 700.
(The cam disc number can also be mapped in FHPP+).
3.
Start: The cam disc mode is started through a rising edge at the START bit CPOS.B1.
Examples for configuration of the controller: see section 6.9.4 and
6.9.5.
